Elementor Pro Posts Widget Live Filter
Elementor Pro is required, as unfortunately the free version does not contain the Posts widget.
Under the Pages submenu, create a new page for this, which is going to be used as the host for the elementor widgets - and will act as the results page.
After creating the new page, open it with Elementor, and open your site admin panel on a new browser tab for convenience.
Create a new page
Edit with elementor for the next step
You can create a new search instance, but use an existing one, if you have one. No special configuraion is required - any search instance will work. If you are new to the plugin, please check the Getting Started section first.
In this tutorial we are using the following configuration.
Before starting a small text is needed - open up the search instance options, and click on the "Toggle Shortcodes for ..." text.
...then copy or take note of the "Elementor Posts Widget Live Filter" input text, we will need that in a moment..
Once the text is copied/noted, create or open an existing page within the Elementor page editor. We are using a two-column page layout. To the left column goes the posts widget, and to the right goes the search shortcode.
Look for "posts" within the widget finder, and drag the "Posts" widget to the desired position (to the left column in our case)
Open up the Posts Widget options, and navigate to the Advanced Options panel.
When done, look for the "shortcode" widget and drag it to position (to the right column in our case)
To the shortcode widget, enter the search shortcode, that you want to use. You can find the search shortcode under the "Ajax Search Pro" menu.
Copy and Paste the shortcode into the shortcode widget, hit "Apply" and save the page.
That's it! Open up the page, clear the cache, and the plugin should now actively filter the posts widget!
If the plugin shortcode is present on the same page as the widget, the alternative search triggers are automatically activated - these override some redirection/live search behaviours.
These override triggers can be configured on the same options panel, General Options -> Logic & Behavior
Please read each option hint for its exact purpose.
