Because of the way the Attribute tag works they aren't part of any of the templates so you'll have to add it.

Say you were using the Slide template for your Gallery. Open up the header.html and add your attribute tags. In the area you want them to show up. In your case it would be something like Industry: [Attribute:Industry] Material: [Attribute:Material] and Color: [Attribute:Color].

My suggestion would be to make a copy of the Slide template (or whatever template you're going to use) and make your changes to that one.

Lior,
Yes you can accomplish exactly what you want to with the attributes feature in the current build.

On your Repository's module settings page, create 3 attributes, Industry, Material and Color. Then click on the Industry Attribute in the attributes list and begin entering Values in the value box to the right. Repeat this for each of the 3 attributes. Now, when you upload items to this repository, you will see 3 sets of checkboxes, one for each attribute with checkboxes for each value.

As Mike said, you will have to create a new skin, or edit an existing one. The best way to start would be to copy the default folder under the DesktopFolders\Repository\Templates folder, paste it in the same location and give it a new name, for example, gallery.

Now, in the DesktopModules\Repository\Templates\gallery folder, edit the header.html file with notepad. If you are not also using Catgories, you may delete the [CATEGORIES] tag. Next, add 3 new tags, [ATTRIBUTE:Industry], [ATTRIBUTE:Material] and [ATTRIBUTE:Color]. At runtime, the tag will be replaced with a dropdown list that contains all of the valid values, plus an 'ALL' option. By selecting various combinations of the 3 dropdown lists the users will be able to filter the repository just as you wish.

The final step is to go back to your Repository module's settings page and set the Repository skin to your new 'gallery' skin.
