Hi,
So right now you are displaying a portfolio of 3 items that you've added with the Page Builder? And you want the link on the bottom to point elsewhere (pages) than the individual portfolio item?
There are a couple of different ways you can go about doing this:
1) Use 3 columns in Page Builder. To each column add directly the page you want the link to go to
2) Use 3 columns in Page Builder. Create 3 additional pages, whose only purpose is to show one of the three images, a blurb of text, and a button that links where ever you want.
3) Use 3 columns in Page Builder. To each column add Direct Text Input, and using regular html tags add/style any image, any description, and any style link or button that points where ever you want.
I think choice #3 would be the easiest to accomplish and be the most flexible.
As to your other question , could explain what you mean by this statement " recreate a 'post lik'e image/video with test and a read more link to a page". 'with test'?
Thanks,
Nick
