====== Teaser: Clear areas if no content available ======


If there is not Content for the teaser available, you can use this snippet to kill entries in the header and footer of the template from CP before delivery. Like that the output of the CP-title or the container avoided if no content is present.

In teaser template we have to insert additional tags.

===== Description: =====

- To identify this CP, it is important to place the entry ##%%<!--TEASERX_01//-->%%## into the head area of the template, analogous to the entry in the script.

- If there is no content available, all messages between ##%%<!--TEASERX_LEER_01//-->%%## and ##%%<!--TEASERX_LEER_02//-->%%## are removed.

- Additionally you have to insert **%%<!--TEASER_ENTRY_START//-->%%** ##%%<!--TEASERX_CONTENT//-->%%## **%%<!--TEASER_ENTRY_END//-->%%**.

##**%%<!--TEASERX_CONTENT//-->%%**## serves as a simple mark to determine whether content is present or not.
