Configure browser to only show a subset of collections

[hrodmn]

I have a STAC deployed as an API with stac-fastapi-pgstac that has several distinct types of collections. I think these sets of collections would fit nicely in a set of sub-catalogs, but as discussed here I don't think it is possible to configure stac-fastapi or pgstac to do that. In order to make the collections more browsable I would like to display them in separate instances of stac-browser.

Is it possible to configure the stac-browser to only read a subset of collections by filtering on some collection-level property (e.g. keywords)?

There are two main options:

• Expose individual catalogs via stac-fastapi, this needs some code changes on your side. Then you configure STAC Browser to only read the catalogs with apiCatalogPriority set to childs.
• Alternatively, you go forward with your proposed solution and you add a preprocessSTAC function in the config that filters collections. But this seems like an akward hack.
