The easiest method to make a <label> clickable is to give an ID #checkbox to the checkbox, and to add a custom attribute for="checkbox" to the <label>.
But foris reserved by Webflow:
So another method to achieve that: the <label> should include the <input>. It’s actually a very good HTML practice for accessibility.
So instead of:
<label for="cheese">Do you like cheese?</label>
<input type="checkbox" name="cheese" id="cheese">
use:
<label>Do you like peas?
<input type="checkbox" name="peas">
</label>
In Webflow the code for a checkbox doesn’t support that yet (and you can’t modify it)
But you can use a custom code box inside of the form block
Now the size of your <label> is your click/touch area.
Just avoid 2 things in order not to break accessibility:
don’t put a link inside the label
don’t put anything else than text and the input inside the label
edit: did the demo with a checkbox, apply to radio of course.
