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.
