css3dropdownloadmenu

Posted by & filed under Tips and Tricks, wordpress.

At first look at the demo of a pure css3 dropdownload menu. For more details see the main post link here.


I was thinking to make the default wordpress drop down menu like this and I just tried and did this. Though you may need little adjustment if you use this with any custom theme. Also I added the dropdown menu with my custom theme used in idea52.com. See my output

So let’s make the default top dropdown menu like above. We need to play with our default theme stylesheet style.css. Open file style.css file from theme twentyten and find the line

/* =Menu
-------------------------------------------------------------- */

And find code like

/* =Content
-------------------------------------------------------------- */

We need remove code or replace all css code between those two line and paste with the following code.

#access {
	/*background: #000;*/

	float: left;
	margin: 0 auto;

Oh we need to add few lines in functions.php file for better support

open functions.php file and add at last

function walker_nav_menu_start_el_adddepth($item_output, $item, $depth, $args)
{
    $item_output = str_replace('<a href="', '<a class="level_'.$depth.'" href="',$item_output);
    return $item_output;
    
}
add_filter('walker_nav_menu_start_el','walker_nav_menu_start_el_adddepth', 10,4);

Also note that the css code will not work exactly if browser is not css3 supported or need to add some exception rules in some cases.
Wait wait, you can do the same thing for joomla1.5 default template’s pillmenu(top main menu) and replace the pillmenu css with following, I think you know where to edit, if not then find yourself, I am busy.

/* horizontal pill menu */

    Rashedul Kabir: I see you are using the menu here… but another thing i notice is that the bar is a bit flickering when mouse is hovered on the menu, any short hack that can solve this?

    Actually same css will not give exact output always or in all sites because css class or id gets override. It’s flickering because in some pages no top menu is selected and when mouse hover is done it’s puts extra border in menu and that is increasing height.

    Hack can be done like in normal mode (if not active or mouse hovered state) then for normal anchor tag we can put border of same width but color will be background color of the menu row so that top level menus always get same height if active, hovered or normal :)

    This is awesome… I just started reading about css and web layouts and this is something that seemed to be another magic to me… hope i can implement these on the proper place… thanks for the share and a very nice post indeed.
    :)
