* eTemplate Extension: widget that shows one row of tabs and an other row with the eTemplate of the selected tab
|
|
*
|
|
* You can use etemplate::setElementAttributes($name, 'tabs', array $tabs) to define tabs on runtime.
|
|
* $tabs is an array containing an array for each tab with following (eT2 compatible) values:
|
|
* - 'label' label of tab
|
|
* - 'help' title/helptext of tab label
|
|
* - 'template' name of template
|
|
* - 'id' optional namespace for template (actually 1. grid in template)
|
|
*
|
|
* See the example in 'etemplate.tab_widget.test'
|
|
*
|
|
* This widget is independent of the UI as it only uses etemplate-widgets and has therefor no render-function
