Help in Dropdown filter for repeaters

Hi
I’m trying to have dropdown filter for my repeater , and i am not really expert in coding , this code will help me reducing 90% of my website pages .
I just want an example for filter code with dropdown selection to filter the data displays in the repeater.
"example for this , my dataset name is engineering jobs , and i want to filter the repeater based on the sub-categry which can be electrical , or mechanical, etc … , so the page will be loaded with all jobs related to engineering and i need this dropdown to allow users to filter the display as per their selected sub-category .
I made this option work by doing pages and increase number of repeater based on number of sub-categories which increased number of my website pages to a huge number .
Thank you in advance.

You will probably find the Cascading Form Example very useful.

Thank you :blush: , i will try and let you know the result

Hello Yisrael ,
I spent full day trying to get any code working , but unfortunately i couldn’t get any code working ,
I will share my page URL , if you can have a look and advice sample of this code and i will repeated in the entire site .
1- This page which i need to apply the drop down filter
https://www.freemunity.net/find-project-all-writing-editing

2- This page includes values which i need to put in the drop down filter in the first page
https://www.freemunity.net/find-project-subcat-writing-editing
" Existing website been published with an individual page for each sub - category , so you can imagine how many pages i did for all sub and main categories "
and now , i need this code to use only one repeater page with sub category drop down filter, for each main category . This will reduce number of pages from 30 to 1 !

That means i need to jump from this main page " https://www.freemunity.net/find-project-main " to the page mentioned in the first point .

I hope that i delivered the idea clearly .
I will be very thankful for helping me getting sample for this code .
