I would like to filter a list lookup by multiple values. There are several disuccions about this topic but no one fits into my solution.
Basicaly we have a data structure like a tree:
+- 1.1 ---+
| +- 1.1.1
Now I want to filter the lookup based on the level in the structure. If I navigate to 1.1, I want to filter the lookup for each data under this level. I have all data in place, but I cannot attach multiple values to the list lookup filter (Control Settings->Filtering->Filter available selections->By aspecific value). It is not possible to use some kind of or-statemants like || or the or-function of Nintex.
A CAML Query would be the nicest solution:
<FieldRef Name='FIELDNAME' />
Try it first on a CAML tool, for example >>> SharePoint CAML Query Helper for 2007, 2010, 2013, Office 365 SharePoint Online - Home
Unfortunately you can do it in List View control, but not in List Lookup control.
