Shouldn't you set a height limit where the playlist descriptions are very long? I don't see anything related to a height limit in the view you added.

[SameenAhnaf]

What about this type of approach? Two lines of description with a More button for expanded view.

Two lines of description with More option:

Expanded view after clicking More:

[AudricV]

Two lines is probably a bit too short, but the idea is very good. For consistency with other UI elements of the app, we may use an alert dialog to display the full description.

[TobiGr]

AlertDialog? Are you sure? I'd just expand the description like it is done with comments

[AudricV]

Wouldn't we get the same size issue we want to avoid when the description is expanded?

[opusforlife2]

No, because in this case it would be the user who chooses to expand the description.

I'm assuming tapping on it again would contract it?

[wb9688]

I don't think it's that great to have such a small 'Show more' button next to the 'Pop-up' button. Why is it not like comments?

[TobiGr]

@wb9688 I used the button to explicitly state that there is more content. The problem with the current comment implementation (i.e. three dots as indicator and click for more content) is the bad accessibility. Three dots at the end do not indicate the action that can be taken, a text clearly does.

I increased the gap between the playlist actions and the show more button.
