feat(gui): add stable CSS classes to QuickAdd's pickers

[chhoumann]

QuickAdd's pickers now carry their own CSS classes so users can restyle them with a snippet:

• qa-choice-suggester: the QuickAdd launcher and Multi choices (ChoiceSuggester)
• qa-suggester: single-value pick lists such as {{VALUE:a,b,c}}, the input suggester, and quickAddApi.suggester (SuggesterModal), plus the existing-note picker for Template choices (TemplateNoteDiscoveryModal)

Obsidian opens every picker (.prompt) 80px from the top, while text prompts are centered. QuickAdd follows that default. Before this change, a snippet could only target .prompt, which also moved the command palette, the quick switcher, and every other plugin's picker. The classes are added to modalEl (the .prompt element) in onOpen.

The Controlling Prompts docs get a short "Style pickers with CSS" section listing both classes, with a snippet that centers QuickAdd's pickers on desktop. I tested that snippet in Obsidian 1.13.7 as a real .obsidian/snippets file enabled through Obsidian's snippet toggle, 800px-tall window:

• The Multi picker, api.suggester, and the following Title prompt all center at y=400.
• The command palette stays at 80px.
• With mobile emulation, the picker keeps core's position (115px).

tests/e2e/suggester-classes.test.ts opens all three pickers in real Obsidian and checks for the classes, so renaming one (which would break users' snippets) fails CI. It fails on master and passes here. Lint and all 5758 unit tests pass, and the docs build.

This replaces the approach in #1799 (QuickAdd centering its pickers itself), which is now a draft and will be closed.

Refs #1796

Note

Add stable CSS classes to QuickAdd pickers

• Adds qa-suggester to SuggesterModal.ts and TemplateNoteDiscoveryModal.ts via onOpen, and qa-choice-suggester to choiceSuggester.ts
• Documents these hooks in a new "Style pickers with CSS" section of ControllingPrompts.md, with a desktop CSS example
• Adds an end-to-end test in suggester-classes.test.ts that verifies the classes on the choice launcher, API suggester, and template note-discovery picker

Summary by CodeRabbit

• New Features
  • QuickAdd choice pickers, generic suggesters, and existing-note prompts can now be styled independently using the .qa-choice-suggester and .qa-suggester CSS classes.
  • Added documentation with a CSS example for centering pickers on desktop. Centered pickers reposition as the list changes while you type.

📝 Walkthrough

Walkthrough

QuickAdd picker modals now receive CSS classes when opened. The documentation describes the classes and includes a CSS example. An end-to-end test checks the classes on the relevant prompts.

Changes

Picker CSS classes

Layer / File(s)	Summary
Add and verify picker classes docs/src/content/docs/docs/ControllingPrompts.md, src/gui/GenericSuggester/SuggesterModal.ts, src/gui/TemplateNoteDiscoveryModal.ts, src/gui/suggesters/choiceSuggester.ts, tests/e2e/suggester-classes.test.ts	Documents the picker classes and a desktop styling example. Adds qa-suggester to generic and existing-note pickers and qa-choice-suggester to choice pickers when they open. The end-to-end test checks the classes on the prompts.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Merge Risk: ⚪ Minimal · up to 7721a

The picker styling hooks are added, and no concrete styling failure is established. Available evidence does not show whether the classes miss the prompt element.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 7721a

The new picker classes create a compatibility commitment for user CSS snippets, but the reviewed behavior does not change who can open a picker or what a selection does. No security concern was established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The identified new exposure is that CSS can distinguish these QuickAdd picker modals from generic prompts. The reviewed additions do not establish a new path to execute a choice or reach a privileged sink.

Trust Boundaries and Controls

• observed — The test's plugin-data patch and dev.evalJson calls occur in the E2E test that opens existing APIs; the production modal overrides only call the parent opener and add CSS classes.

With class names placed when they appear.
The pickers shift; the docs explain,
Tests check each class along the chain.
Then off I hop through fields of green.}
