User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.1) Gecko/20060111 Firefox/1.5.0.1

In Firefox 1.5 and 1.5.1, setting the CSS display property to 'none' or 'hidden' and then setting it to 'visible' seems to work, except that the select elements no longer drop down.  

They continue to allow selections by using the keyboard to scroll through options, it is only the display of the drop down that doesn't occur.  

Reproducible: Always

Steps to Reproduce:
1. Set a DIV element which contains a form with a select element and set its CSS display property to hidden or none.  
2. Set the DIV element's display property to visible.

Actual Results:  
Select element does not produce drop down box.  

Expected Results:  
Select element should produce drop down box.

Confirmed Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20060214 Firefox/1.5 ID:2006021404

The category should probably be changed to CORE: Layout Form Controls.

I have a testcase for this, which I'll attach shortly. Updating summary. I can see the bug also in Mozilla1.7.12, so no (recent) regression.

This worksforme on Linux, but it does that with older builds too.  Is this still an issue?

Comment 5

[Martijn Wargers (dead)]

Yes, still an issue, using the latest trunk build on windows.

[Boris Zbarsky [:bzbarsky]]

Sounds like a Win32 widgetry issue, at a guess...

Comment 8

[Ryan VanderMeulen [:RyanVM]]

As bug 371093 pointed out, it can be inside a form as well.

Comment 9

[Martijn Wargers (dead)]

Maybe bug 352093 could fix this?

[Marian POPESCU]

Is bug 369599 related to this?

This worksforme in the latest 1.9a3 on win32; please renominate if that's not the case (or close if it's fixed).

Yeah, this is worksforme, using:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a3pre) Gecko/20070325 Minefield/3.0a3pre
I guess fixed by the "use less views" bug?
