We need a single CMS page or static block which can be loaded from category page in Magento 2 which displays all the sub categories of one parent category which is used for Brands listed alphabetically A-Z. On our previous Magento 1 site it was like so:
https://m1.natureshealthbox.co.uk/brands-a-z
However we do not need the A-Z filters at the top to open a new page all it should do is scroll down or display just the brands in "A" for example. Clicking the brand name itself should simply open the brand page which is a sub category page. Someone has attempted to code this on the link below which would be a static block.
We're currently using Magento 2.3.4 with PHP 7.2. Our Brands category has 500+ sub categories. We would expect this to be developed on a blank Magento 2.3 vanilla install and functionality sent via screenshot/video we then pay you release code we can then install on our staging site test then roll out on production.
