I am creating an application where I want to use the value of the pagepath-field to become the name of span class-name inside a listpage-module…

The value I can get inside a listpages module is %%form_data{pagepath}%% or %%form_raw{pagepath}%%.
The first one will give me the title of the page, the second will give me the %%fullname%%.

I need a unique value so the title is no option since some titles can start with the same words AND I need a value that can be used as a name for a span-class… so no ":" included… which makes %%form_raw{pagepath}%% unusable.

I would sugest a new value for the listpages-module:

%%form_raw_name{pagepath}%%  and in one go
%%form_raw_category{pagepath}%%

IMHO…that should not be so difficult to achieve. It's trimming the %%form_raw{pagepath}%%-value, that's all.
