The extension ke_search has a search field plugin that I want to insert into my fluidtemplate and show on every page. I am very new in this and don't know how to start. Any help is appreciated.
You can assign the Plugin to an typoscript lib:
lib.searchMask < tt_content.list.20.your_plugin
(Please search the location of the plugin in the typoscript browser)
In your fluid you can use f:cObject
to include it:
<f:cObject typoscriptObjectPath="lib.searchMask" />
