Yes, you can use the syntax [link-library categorylistoverride=”99″] where the number of the ID of the category to be displayed.
I tried but while entering only one id it also shows me the links of the other category.
Sorry for the lack of response. I was extremely busy with work travel during the fall.
I am trying to reproduce what you are saying, that using the categorylistoverride parameter on the [link-library] shortcode is not restricting links displayed to the category you specify. The only thing I am wondering is if you created a hierarchy of categories on your site. Do you have a single top-level category, with a bunch of sub-categories underneath? That is the only way I could imagine that setting categorylistoverride would not limit the display of links to the category specified.
