Hi all!
I am making my first website with bricksbuilder.
I need to add many posts. In post I need simple slider with 1-5 slides - https://i.imgur.com/QtGHI8n.png.
I add template for single post, ass slider and now I think how to add 3 - 5 images to the post in an easier way and display them dynamically in the bricks slider.
Must I use ACF or Jet engine (my favorit product) or exist more easy way?
Hey @filandor Welcome to the forum and to Bricks.
If the images need to be different for each post, then yes you are correct, You will need to add them via custom fields i.e. metabox, ACF, JE etc., and then add the images to each post via the new custom fields you have created.
If the images will be the same on all posts, then you can just add them directly from the media folder to the slider in the template.
Good luck building your 1st new Bricks website 
I add Jet engine…
Jet engine gallery field cant use, becouse for render it need elementor Jet engine wiget. So, I add 5 media fields…
Then in single bricks template I add slider with 5 slides each link to img field aded by JE.
All works, but if in my post exist only 3 images - slider shows 5 slides, 2 of which are blank…
How can this be resolved?
Slider has section “query loop”… Its only for show posts? Or can dynamicly generate slides from custom fielsf?
Ideally, of course, display the JE gallery, but probably this cannot be done using Brix yet
maybe exists another way?
You can use the Carousel element. It supports the JetEngine meta field.
Hey @filandor
Yes, that would be the correct behaviour as you saved 5 slides in the original template, so if you used 3 then there would still be the two left over and would be blank as they are not used.
I am not overly familiar with Croco (Jet Engine) But with the others, I would look at it either being a repeater or if you are confident with a little PHP they have just released conditional logic but I am not sure if it yet extends to being able to set a condition where if the custom field is empty, in your case the image has not been added then it will not show the blanks slides.
Here is the doc for it: Filter: bricks/element/render – Bricks Academy
But again not sure if it supports custom fields and or Jet Engine
I would look at it either being a repeater
Jet Engine also have repeater (image picker).
If I will be have repeater, how link it to bricks slider… dynamycly generated slides from repeater? Or is that not what you meant?
awesome!!! Its worked, thanks
