Materialize TextArea无法动态调整及页面联动问题求助

Hey there! I've run into this exact problem before, so let me share some troubleshooting steps that worked for me:

• Double-check your Materialize CSS import
  Make sure you're using the full, unmodified Materialize CSS file (not a custom build that might have stripped out forms-related styles). The automatic resizing for materialize-textarea relies on specific CSS rules that handle height adjustment as content grows. If those rules are missing, the textarea won't expand properly, and the page won't reflow with it.

• Inspect parent containers for conflicting styles
  Even if your textarea doesn't have a fixed height, check its parent elements. If any parent has overflow: hidden, height: 100%, or position: absolute set, it might be preventing the container from expanding when the textarea grows. Use your browser's dev tools to inspect the DOM tree and look for these restrictive styles on ancestors of the textarea.

• Avoid overriding Materialize's default textarea styles
  Check your custom CSS to make sure you aren't accidentally overriding properties like height, max-height, or resize for the materialize-textarea class. For example, if you set resize: none or a fixed min-height, that could break the automatic resizing behavior.

• Verify no JavaScript is interfering
  Even though the docs say no JS/jQuery is required, sometimes other scripts in your project might be modifying the textarea's dimensions or preventing the browser's default reflow. Try temporarily disabling other scripts to see if the issue goes away—if it does, you'll know there's a conflict to resolve.

• Test with a minimal working example
  Create a stripped-down HTML file with just the necessary Materialize CSS and your textarea code. If it works there, the problem is likely in your project's other styles or scripts. This helps isolate the issue quickly.
