creating a drop down menu

t_henson · Posted: Sat May 19, 2007 12:06 pm

i am looking for a way to have a drop down menu when you rollover an image. i have found ways to do it with just text links, but not with an image. any help with pointing me in the right direction?

Actually, the two should be quite similar. Instead of using the "onclick()" event, you would use "onmouseover()" to show the menu and then "onmouseout()" to then hide the menu.

okay, well i guess you cant used css style or javascript in header.html?

t_henson, actually, use external files and then add the links to them in includes/javascript.php. Then you can call the functions / etc. from your main content / blocks / header / whatever just fine.

okay i added the css style and the javascript functions to javascript.php and then added the onmouseover() info in the header.html file but i cant get it to work.

Please post your header.html file here if you don't mind (unless it is riddled with javascript). Otherwise send it and your .CSS and .JS files to me at montegoATmontegoscriptsDOTcom and I'll take a look.

only A supports the :hover pseudo.
Therefore use <a><img></a>

hi i am trying to use javascript functions in my nuke header as well but with no luck. Can you please help? Thank you.

candy, a link to your site which has the changes you have made would be helpful. Also, having some idea of what you are trying to add... thanks.

thanks...i haven't actually made the changes because if i overwrite my current header it will be screwy. so i am waiting to fix the header before overwriting my current one. i basically took my header and am adding a row that has a drop down menu in javascript but when i go to test it on the site, the script doesn't work because the drop down isn't shown. any ideas on why this isn't working? thx!!!

Maybe you can PM me a link to your site as I really want to see the end result when the HTML is generated. Wink

i dont' have the header on my site because it is faulty. i have it on my site as /header3.html instead of header.html and by itself it shows up. only when i plug it into the header.html file does it not work. in other words, i don't have it as part of my site now because the drop down doesn't work. i was hoping to troubleshoot and resolve it before i upload it as my new /header.html file. thankx!

candy · Posted: Mon May 26, 2008 10:18 pm

any ideas on how i can get this jscript header to work for the drop down menu? thanks!

montego · Posted: Tue May 27, 2008 6:18 am

candy, its on my list, but I have things ahead of it. Once you said that I cannot see the generated HTML, it makes my job that much more difficult and takes time that I have very little of. I'll get to it. Sorry that I cannot give you a date as to when... Sad
