When the slider is set to PER VIEW: 1, the slider block is infinitely enlarged．
Ｕnder the slider, two slides are added. PRE VIEW cannot be set to 2, otherwise it will be infinitely enlarged.
Hi @loveczj,
Sorry to hear you’re experiencing trouble with this.
In fact, this is happening because you have placed the Slider block within a Columns block, which causes it to grow infinitely.
To avoid the enlargement, be sure to set the overflow to hidden.
Please let me know if this helps!
Hi @Araminta
Thank you for your help, the problem of infinite growth has been solved.
Now there are two new questions
1.When the dot is enabled, it can be displayed on the backend, but the front page cannot be displayed.
2.How slide implement dynamic query ACF gallery
Hi @loveczj,
Thanks for getting back to me!
Glad to hear the infinite growing is resolved. 
As for the Slider block dots, unfortunately I haven’t been able to reproduce your error.
Could you possibly provide me with a screencast of the issue or send a temporary access to support@cwicly.com, so that we can take a closer look at this? Thank you in advance.
It isn’t currently possible to implement a dynamic ACF gallery in the Slider block. This is planned for the dynamic slider.
However, in the meantime, you could use the Repeater block and enable the Slider feature.
Here is a video demonstrating this: Repeater Dynamic Slider - YouTube
Please let me know if that helps!
