Displaying lists with restricted number of products with Jquery

[anonymo...@gmail.com]

I am using jquery to present a number of products as per user's selection on "Show" dropdown menu. If user selects to get 9, 12, 16 or 20 products per page it should show accordingly in my list view.

Following is the code for HTML:

<form>
<span>Show:</span>
<select class="orderby number" name="page_size">
                                               <option value="9" selected="selected">9</option>
                                               <option value="12">12</option>
                                               <option value="24">24</option>
                                               <option value="36">36</option>
                                               <option value="48">48</option>
                                               <option value="60">60</option>
                                               <option value="90">90</option>
                                               <option value="100">100</option>
</select>
</form>

My list view varibale is:

items = Items.objects.all().

How can I restrict to load products according to the user's selected number of products?

Please help.

Regards,

Slicing a list like you are trying to do is calling a pagination.
Django have a few tools for dealing with this problem. Here is a link
to the documentation:
https://docs.djangoproject.com/en/1.11/topics/pagination/

If you have any trouble using it, don't hesitate to ask for more details :)
