To refine a thumbnail grid / results, I see two ways
- Using dedicated sites with thumbnail grids
You could use menus / sub-menus pointing to thumbnail grids with specific categories filtered, e.g.
WORK
Sub-Menu: PHOTOGRAPHY
Link to Site showing Thumbnail Grid with filter PHOTOGRAPHY
Sub-Menu: DESIGN
Link to Site showing Thumbnail Grid with filter DESIGN
--> This way requires users to switch between "sub-categories" in the menu
--> It also means, you have to set up multiple thumbnail grids
- Using tags
As far as I know, the original use of categories is to link only 1 category to a project (I read that this is also better for SEO). Tags can be used multiple-times on 1 project/site, etc.
In the thumbnail grid the default of tag filters is "OR". E.g. you have a project that can be assigned to a photography, but also shows interior, you can assign the tags photography and interior.
--> This ways allows to have basic categories and tag bubbles right on one site, users can filter at one place
--> You need to make sure your projects fit into this meta-structure
