@nicowob can you test out the contact forms with the new update (1.5.1)? I’ve made minor changes to the popup behavior, and in 9/10 cases the select list works perfectly now.
However, there are some cases when the select list still closes instantly in Firefox – this has to do with the Divi-styling and is not limited to contact forms inside a popup but also happened for contact forms inside the normal page content.
The reason seems to be the top/bottom padding of the select list (which adds the space in the top/bottom of the dropdown list). This is how Firefox behaves and unfortunately, there’s no way to fix this via javascript…
Here’s an example of the issue with a non-popup contact form. You can see that the issue happens every 3rd click when clicking on the top or bottom padding: https://www.screencast.com/t/sxMsdK2rk
Update:
I did some further tests with CSS and had success by adding this CSS code to the page:
.popup .et_pb_contact_select {
-moz-appearance: textfield;
}
Can you test this and let me know if this also makes the select list work correctly in your case? When it does, I will add the CSS to the plugin.
Also, do you use Windows or a Mac/Linux?
Thanks for your feedback! Philipp
