Hopefully this is quite a simple question with quite a simple answer but not having a great deal of experience with parse files and MySource tags etc I thought I'd seek some advice.
I'm looking at adding a new nested content area to our site's parse file in order to get Google Tag Manager's script to appear directly after the body tag on all pages.
On the surface it looks like all I need to do is add something like this after the body tag in the parse file then I'm good to go with nesting the new code snippet via our main customisation:
You would then need to create a Design Customization to configure the nested area. After you have done that, make sure to apply the design customization to the pages/site that you want by going to the Settings screen of those assets.
Thanks Nick. Is updating the parse file process heavy in Matrix i.e. is it a big ass Hippo job or just a quick refresh?
Also I'm assuming it won't have any effect on current customisations until I configure the new area? At the moment we only have a handful of customisations I just want to avoid breaking anything on the front end.
The Hipo time depends on how larger your parse file is and number of customizations.
If you have a top level customization then you can configure the nested content area into that one. If not, you will have to do it for each customization where you are wanting to use the nested area.
