I've been kinda quiet around here lately.
But, I've gone and done it. I've added some stuff so that you can specify which category or categories you would like to include in your calendar. This is done thus:
- Code: Select all
[[ calendar category="category-one,category-two,category-three,etc." ]]
Of course, you would use the names of your categories (
not the display names, the "internal" names). For instance, if you had a category with the display name
My Ramblings you would use
category="my-ramblings". If you do not use the parameter, every category will be displayed, just as it worked before this update.
Hopefully, I haven't stepped on any toes doing this.
Here's the code:
- Code: Select all
