Hi,
We have a business requirement where the client want us to develop a Core Results webpart he can put anywhere. The problem is that it is quite special: it must have a set of library folders as parameter (those can be as many as one wants while selecting in any level of the tree) and after saving that parametrization the webpart should show a dropdown list with one entry for each folder the user selected in the parametrization. The search should only show results for a search in the folder that is selected in the dropdown, and its subfolders.
We thought on doing this by placing a treeview as a webpart parameter and then saving the folder the user selects in that treeview. After searching quite a bit I've found no idea how to do this, can anyone help?
