How can I fix the issue of the select (dropdown) button on Webflow not displaying the correct styling on mobile browsers (Chrome and Safari) for iPhone?

TL;DR
  • iOS limits CSS styling for <select> elements, so use appearance: none and custom CSS for partial styling improvements.
  • For full control, build a custom dropdown in Webflow using Divs and interactions, or wrap the native select in a styled Div with a custom arrow icon.

The issue occurs when the native styling of a <select> dropdown on iOS overrides Webflow’s custom styles, especially on mobile Safari and Chrome. To resolve this, you'll need to apply mobile-specific adjustments and accept some limitations of native dropdown rendering on iOS.

1. Understand Native Limitations on iOS

  • iOS does not allow full CSS styling for native <select> elements, including font size, arrow icons, padding, etc.
  • Safari and Chrome on iPhone both use the same WebKit engine, so styling restrictions are the same across both browsers.

2. Use Webflow’s "Custom Dropdown" Structure (Optional)

  • For full styling control, consider replacing the native <select> with a custom dropdown built using Webflow's Div blocks, interactions, and text elements.
  • You'll get complete control over visuals, but you’ll lose native form behaviors (keyboard navigation and mobile picker UI).

3. Improve Mobile Styling of Native <select>

If you want to keep the native form element and improve its appearance:

  • Set width to 100% of the parent container to ensure mobile sizing is consistent.
  • Remove browser-default styling by adding the following custom CSS in the page settings or site-wide:

  • appearance: none;  
  • -webkit-appearance: none;  
  • -moz-appearance: none;  

  (Webflow doesn't allow pseudo elements or full CSS injection in Designer UI, so use the site/page Custom Code fields.)

  • Add padding and background styles carefully:
  • For example, set enough right padding to not overlap the dropdown arrow.
  • Set a consistent background color, border, and border-radius.

4. Add a Custom Dropdown Arrow (Workaround)

  • iOS hides custom arrows. To display a consistent arrow:
  • Wrap the native <select> in a Relatively-positioned Div.
  • Place a custom arrow icon (SVG or image) inside the wrapper using absolute positioning.
  • Ensure the arrow doesn't interfere with the dropdown’s click area.

5. Test on Devices and Adjust Viewport Fixes

  • Use Webflow’s preview mode along with actual device testing.
  • Force mobile view using Developer Tools in Chrome, Safari, or Xcode Simulator for more accurate previews.

Summary

iOS restricts custom styling of <select> elements, so use appearance: none, wrap the field for extra styling (including custom arrows), or build a fully custom dropdown in Webflow with Divs and interactions for full control.
