after declaring some folders in a page, the option to select a folder appears in the cms page.

but the name of the dropdown box is "folder", can this be changed to another title like 'job type'?

[KK]

I assume you mean the dropdown as it appears in the admin-panel.

We cannot do it out-of-box, I'm afraid.
If you are willing to put in a little effort though, you can create your own "Custom admin screens" as described here - http://www.couchcms.com/docs/concepts/d ... forms.html. The sample code there has a custom screen (snippets/default_list.html) that you can tweak.

Hope it helps.
