"repeat selection improved" never repeats anything

repeat selection improved never repeats anything. Regardless of the page or recordset

You should use the standard MySQLi Repeat Region for most applications. The improved one allows more control and allows nesting inside of an existing repeat region, but it won't automatically update the number of rows returned by the recordset. The default is to only return one row.

You can manually update that by changing this line:
$Categories = new WA_MySQLi_RS("Categories",$jay_cms,1);

The 1 at the end is the number of rows in the recordset. You can change that to 0 for all rows, or change it to the number of rows you want returned to be used on the page.

I need to create a navagation drop down, I used to use css menu writer for this.
I have a table jaycms_categories I have attached it. I have a created the two record sets
first:
<?php
$Categories = new WA_MySQLi_RS("Categories",$jay_cms);
$Categories->setQuery("SELECT * FROM jaycms_categories WHERE CategoryParent = 0");
$Categories->execute();
?>
second:
<?php
$Subcategories = new WA_MySQLi_RS("Subcategories",$jay_cms,10);
$Subcategories->setQuery("SELECT * FROM jaycms_categories WHERE CategoryParent = ?");
$Subcategories->bindParam("i", "".($Categories->getColumnVal("CategoryID")) ."", "-1"); //colname
$Subcategories->execute();
?>
So ive attached the page ive wrapped the subcategories recordset in repeat selection improved
and categories and subcategories in repeat region.
I do get this result:

“<div class="mega-dropdown-column pt-4 px-2 px-lg-3">
<div class="widget widget-links"><a class="d-block overflow-hidden rounded-3 mb-3" href="#"><img src="img/shop/departments/02.jpg" alt="Shoes"></a>
<h6 class="fs-base mb-2">Bath and Shower</h6>
<ul class="widget-list">
<li class="widget-list-item mb-1"><a class="widget-list-link" href="#">soap</a></li>
<li class="widget-list-item mb-1"><a class="widget-list-link" href="#">Bath Bombs</a></li>
<li class="widget-list-item mb-1"><a class="widget-list-link" href="#">Shampoo Bars</a></li>
</ul>
</div>
</div>
<div class="mega-dropdown-column pt-4 px-2 px-lg-3">
<div class="widget widget-links"><a class="d-block overflow-hidden rounded-3 mb-3" href="#"><img src="img/shop/departments/02.jpg" alt="Shoes"></a>
<h6 class="fs-base mb-2">Hair</h6>
<ul class="widget-list">
</ul>
</div>
</div> “
So subcategories does not stay in the correct parent category.
Also i need the menu to really look like this:
****** Repeat this div wrap Every 3 record*** <div class="d-flex flex-wrap flex-sm-nowrap"> ****** Repeat this div wrap Every 3 record***

<div class="mega-dropdown-column pt-4 px-2 px-lg-3">
<div class="widget widget-links"><a class="d-block overflow-hidden rounded-3 mb-3" href="#"><img src="img/shop/departments/02.jpg" alt="Shoes"></a>
<h6 class="fs-base mb-2">parent category</h6>
<ul class="widget-list">
<li class="widget-list-item mb-1"><a class="widget-list-link" href="#">subcategory</a></li>
<li class="widget-list-item mb-1"><a class="widget-list-link" href="#">subcategory</a></li>
<li class="widget-list-item mb-1"><a class="widget-list-link" href="#">subcategory</a></li>
</ul>
</div>
</div>
<div class="mega-dropdown-column pt-4 px-2 px-lg-3">
<div class="widget widget-links"><a class="d-block overflow-hidden rounded-3 mb-3" href="#"><img src="img/shop/departments/02.jpg" alt="Shoes"></a>

<li class="widget-list-item mb-1"><a class="widget-list-link" href="#">subcategory</a></li>
</ul>
</div>
</div>

****** Repeat this div wrap Every 3 record***</div> ****** Repeat this div wrap Every 3 record***

you can see the example here https://themes.getbootstrap.com/preview/?theme_id=35287
it is the department dropdown on the left.

You probably just need to move the subcategories recordset from lines 9-13 inside of the repeat region after line 27.

That will cause the subcategories to be re-populated with each new category.

You should be able to use a standard repeat region for both of these as well. Since they are different recordsets, they should be able to be nested. The improved repeat region is only necessary for nested repeats of the same recordset, and if you want a fixed number of rows displayed regardless of the recordset results (or even without a recordset).

Worked perfect thank you!
