📝 Walkthrough
Walkthrough
The change defers builder select-option markup and hydrates selects in the admin UI. It batches field loading and initialization. Radio and token-input controls initialize when field settings open, with radio behavior and token proxy styling scoped to the shown panel.
Changes
Shared select options
Layer / File(s)
Summary
Render and defer select options classes/helpers/FrmBuilderSelectHelper.php, classes/views/frm-fields/back-end/autocomplete.php, classes/views/frm-fields/back-end/settings.php, tests/phpunit/helpers/test_FrmBuilderSelectHelper.php
The helper renders select options and defers unselected options on the builder page and during frm_load_field requests. The autocomplete, label-position, and field-type selects use the helper. PHPUnit tests cover selection, fallback, ordering, escaping, and deferral.
Transfer and hydrate option templates classes/controllers/FrmHooksController.php, classes/helpers/FrmBuilderSelectHelper.php, classes/controllers/FrmFieldsController.php, js/src/admin/sharedSelectOptions.js, js/src/admin/admin.js, tests/cypress/e2e/Forms/sharedSelectOptions.cy.js
The admin footer and field-loading responses provide templates to the admin UI. Admin code hydrates tagged selects when settings open, multiselects initialize, or a tagged select receives focus. Cypress coverage checks option order and submitted values across repeated settings openings.
Batch field loading and initialization js/src/admin/admin.js, js/src/admin/fieldLoadBatch.js, tests/cypress/e2e/Forms/formsSettings.cy.js
Field-load responses are processed asynchronously, with errors displayed for failed or invalid responses. Fields render in order and initialize in slices. The settings tests use shared form-creation helpers and updated wait conditions.
Field settings initialization
Layer / File(s)
Summary
Scope radio behavior to field settings js/src/settings-components/components/radio-component.js, js/formidable-settings-components.js, tests/cypress/e2e/Forms/radioDeferredInit.cy.js
Radio initialization uses the field-settings hook. The component avoids duplicate listeners, disconnects observers from the prior panel, scopes related-element lookups, and updates trackers for visible wrappers. Cypress coverage checks hidden and active panels.
Initialize token inputs within shown settings js/src/settings-components/components/token-input/*, js/formidable-settings-components.js, tests/cypress/e2e/Forms/tokenInputDeferredInit.cy.js
Token inputs initialize through the field-settings hook instead of an AJAX batch listener. Proxy styling targets the shown settings container. Cypress coverage checks retained values and proxy styling.

Loading
Merge Risk:🔵 Low · up to 0eaad
A rendering error can leave affected fields stuck loading without an error message. The issue is bounded, but error handling would make field loading more reliable.
Security Architecture Review
Security architecture risk:🔵 Low · up to 0eaad
The new loading flow can leave the form builder partly initialized if processing fails. No security bypass was established, and field loading remains restricted to authorized editors. The behavior of the shipped script and the broader security surface have not been fully verified.
Retained concerns
Low · reliability · inferred: A render or initialization exception during an asynchronous field batch releases its request slot but has no per-field recovery path for unprocessed, claimed placeholders. This is a builder failure-containment concern, not an established security bypass.
Security review details
Security Blast Radius
inferred — The evidenced processing path is confined to the admin form builder and its authorized field-load request. The supplied changes do not establish a new unauthenticated or cross-service entrypoint.
Trust Boundaries and Controls
observed — Permission and nonce checks precede the PHP field response; the browser uses option text rather than interpreting a record label as HTML. These controls do not establish safety for uninspected callers or attributes.
Resilience and Maintainability Implications
inferred — A thrown slice callback can leave the editor with some fields loaded and others still claimed, despite balanced request-slot accounting. No resulting privilege or data-boundary violation was established.
Hardening Proposals
proposed — Consider reconciling remaining placeholders when a slice fails, and checking that the deployed admin script implements the PHP option handoff before rollout.

A render exception leaves the batch's placeholders stuck and hides the error.
handleAjaxLoadFieldSuccess can throw partway through a slice. For example, renderLoadedField or a frm_ajax_loaded_field listener can throw. When that happens, the finally block frees the queue slot, but nothing runs showFieldLoadError for the fields that were not rendered. Those placeholders stay claimed with frm_load_now, so the queue never retries them, and the user sees no error message. The rejected promise also becomes an unhandled rejection inside the jQuery callback.
Add a catch block that reports the remaining fields. showFieldLoadError only changes elements that still have frm_field_loading, so it is safe to call it with every requested ID.

Approve at 0eaada9, with two non-blocking notes (inline).
Verified live (preview env, Lite at this head, SQLite/Playground, no Pro): on a saved 6-field form the five builder selects arrive with 1 option each. Opening the Text field's settings hydrates them to 37 (autocomplete) / 8 (label position) / 13 (field type) options with the saved values intact. A freshly inserted field renders full option lists (not deferred). No placeholders were left loading. formidable-pro's frm_ajax_loaded_field listener iterates frmFields, so per-slice dispatch is compatible.
Source-verified:render() keeps the old "saved value missing → first enabled option" behavior, and the old label-position selected() loose compare maps to the same result for null/false. The committed js/formidable-settings-components.js matches a rebuild of this head once webpack module ids are normalized. js/formidable_admin.js contains the new code (frmOptions, selectOptions, "Unable to load field"), but I couldn't byte-compare it: in my environment all 10 bundles rebuild with different module ids, including ones this PR doesn't touch.
Not exercised: a native-popup mouse click on a deferred select (the panel hydrates on show, before the select can be clicked), the bad-response path (my route-mock repro didn't take effect), Pro, and the perf numbers in the description.
CI: Cypress shard 1 is red on Form Templates page › add templates as favorites… (svg.frmsvg not visible). That spec and the form-templates.js bundle are untouched by this PR, so it looks like a flake [Likely], but I couldn't confirm that from run history. Re-run it before merge. The PR's own specs passed: tokenInputDeferredInit ran in shard 1, and the others sit in shards that passed (I didn't open those logs).

A rejection from handleAjaxLoadFieldSuccess (a throw while rendering or initializing a slice) releases the queue slot but leaves every not-yet-rendered placeholder claimed (frm_load_now), so it spins forever, is never re-requested, and has no message. It also surfaces as an unhandled promise rejection. The old synchronous handler had the same gap, but the new async slicing widens it, and showFieldLoadError() already exists for this. It only touches placeholders still carrying frm_field_loading, so calling it for the whole batch is safe. CodeRabbit raised the same point on this line. Source-verified, not reproduced.

hydrateBuilderSelectsIn() has one call site (showFieldOptions() in admin.js) and a one-line body. It isn't complex enough to earn its own export. Inline singleField.querySelectorAll( 'select[data-frm-options]' ).forEach( hydrateBuilderSelect ) at that call site and drop the export. Non-blocking: it causes no defect.

Expected 'this' to be used by class method 'hideExtraElements'
If a class method does not use this, it can sometimes be made into a static function. If you do convert the method into a static function, instances of the class that call that particular method have to be converted to a static call as well (MyClass.callStaticMethod())

Use of insecure md5() function found
Using md5(), sha1() function is not recommended to generate secure passwords. Due to its fast nature to compute passwords too quickly, these functions can become really easy to crack a password using brute force attack.
It is recommended to use PHP's password hashing function password_hash() to create a secure password hash.
