You can specify a visibility condition on a web page element. It will only be visible if the condition is respected.
To add a visibility condition, select a block and enter the condition to be respected in the Visibility condition field in the palette.
This option is only available for the following elements: ADDRESS, BLOCKQUOTE, CENTER, DIR, DIV, DL, FIELDSET, FORM, H1, H2, H3, H4, H5, H6, NOSCRIPT, OL, P, PRE, UL, TR, TD.
The expression editor is presented in the Advanced expression editing section.

These conditions adopt the XTK expression syntax (e.g. context.profile.email !='' or context.profile.status='0'). By default, all fields are visible.
Uwaga:
Non-visible dynamic blocks like drop-down lists cannot be edited.
Uwaga:
A condition cannot be defined for a block that already contains a sub-element with a dynamic content or a block that already makes up a dynamic content.
