Blogpost doesn't allow different layout of photos?

I’ll try to explain it through steps.

  1. In your collection template create the 2 different layouts each one of them wrapped in a div called layout-1 and layout-2 or whatever you want them to be called.
  2. In your collection settings create a switch called ‘layout change’ or something similar
  3. Turn the switch on you just created for the blog posts you want different
  4. Select your layout-1 div and go to Conditional visibility, select the option ‘layout change’ and select ‘It’s on’
  5. Select your layout -2 div and do the same thing but now select ‘It’s off’

Once you’ve done this you have a changing layout collection depending if your switch is on or off for each blog post.

NOTE: You can do this with as many layouts as you want you will only going to need to create more conditional visibility rules in order to make it work.

I hope this make sense.
