Walkthrough

The changes introduce a new error message key, missing_fields_error, to both English and French translation files. The TabPanel component was updated to always render its children inside a nested Grid container while controlling visibility via the hidden attribute. In the BlockEditForm component, a new error handling callback was added to display a localized toast notification when required fields are missing during form submission. No changes to component signatures or public APIs are present.

Poem

A bunny hopped into the code today,
To help with forms that go astray.
Now missing fields will show a toast,
In French or English, as you boast!
Tabs now hide with CSS flair,
Bugs are gone—validation’s fair.

  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
