Is there a way to choose how many videos will display on the front page of the UAEL’s Video Gallery? (On the ‘Edit Video Gallery’ widget, there is no opportunity to choose how many videos to display – the gallery just goes on and on – unlike on the posts page, where you can choose how many posts to display on the front page – albeit via WordPress.)
Brainstorm Force's Answer: Currently such feature is not available. Though the alternative way is that you can add only the videos you want to show and delete the other ones.
I don’t find that a satisfactory answer at all!
I think you are asking for pagination like you get with posts, but that is not how a gallery works.
So you may be trying to fit a square peg through a round hole here.
There are some options on CodeCanyon specific for video, that can do that. I haven't looked at it recently, but I know there are options.
