Categories Tree PLUS DropDownCombo ?

[Bonzo]

I searched and tested several categorie-dropdown contribs.

Unfortunately I didnt find a contribution that works in all browsers and shows Categories with TREE and DROPDOWN, this is very important because I need lots of subcategories....

I tried by myself and combined the default tree with a dropdown- contrib, but unfortunately both dont synchronize each other properly as soon as I go deeper than 2nd subcategorie :(

Anyone knows how to fix this code so that TREE, DROPDOWN and BREADCRUMB are synchronized and work in all subcategories ? (or a different contrib working in all browsers ?)

 

This is the spaghetticode I made by combining default and contrib, you can test it by copy and paste it into includes/boxes/categories.php (do not forget to BACKUP)
