It’s 2024 and increasing organic traffic of WordPress blogs or websites is very challenging. Now, we really have to help users through our content otherwise Google will not send traffic to our sites.

On top of that, we will be in a worse situation if we can’t keep the users on our site. It is only possible by offering a good user experience to the users. One of the great ways to satisfy users is to add filtering options to our site. But the question is, how to let the visitors filter the posts of our WordPress site by category and tags?

  • Step – 1. Enable PostX’s Advanced Post Filter
  • Step – 2. Add Post Filter By Categories
  • Step – 3. Add Post Filter By Tags
  • Step – 4. Customize the Filtering Options

Why Let Users Filter Posts on Your WordPress Site

Before going into the detailed explanation of adding filters to WordPress sites, we should know why it is so important. Letting users filter posts has so many benefits. Here are some of the most important benefits.

Find Posts Easily: The first and the most important benefit of filtering options is letting visitors find the posts or content faster. 

Higher User Engagement: Helping users to find what exactly they are looking for faster and better increases engagement. The visitors will be happy and satisfied with the flexibility you are offering to them.

Keep Users Longer on Site: Chances are the visitors would stay more time than they would have been without the filtering options. 

Helps Google to Understand Content Better: The WordPress posts filtering feature not only helps readers but also Google Crawlers. So the posts of your WordPress sites will be fetched and indexed faster and chances are they would rank higher on SERP.

Prerequisites of Adding Filter to WordPress Site

You may know that WordPress doesn’t allow us to enable filtering options by default. So, you have to choose a Plugin to make it available for your WordPress Blog. Don’t worry, we have the perfect solution for you. 

PostX is one of the best plugins that not only offers the Post Filtering feature but also all essential features for creating News, magazines, and Blogging sites.

So, make sure to install PostX, before start adding the post-filtering options to your WordPress site.

How to Let Users Filter Posts by Categories in Your WordPress Site

Now, let’s explore how we can add the post-filtering options by category. You can follow the below steps to properly implement the functionality without facing any issues. You can also watch the video of PostX’s Advanced filter.

Step – 1. Enable Advanced Post Filter

At first, you need to add any of the available post lists or grid blocks of PostX. Then, you need to enable the “Advance Post Filter” from the general settings options, located on the right side.

Enable Advanced Filter

Step – 2. Add Category Post Filter

You can see that three filtering options, Category, Tag, DESC/ASC are already added upon enabling the Filter. You can add more filtering options by clicking on the “+” icon, located on the tooltip.

Add New Filtering Option

Let’s remove all options, and add only the category filter options. For that, click on the list view icon, located on the top left side. Now, remove all other options except the category.

Remove Filterable Items

However, you are free to add multiple or all filtering options at once. PostX offers the following filtering options:

  • Filter By Category
  • Filter By Tags
  • Filter By Order
  • Filter By Author
  • Filter By Ascending/Descending
  • Filter By Custom Taxonomy
  • Filter By Published Order
  • Search Filter
  • Filter By Advanced Sorting

Step – 3. Choose Between Dropdown and Inline Filter

You have two options for displaying the category filtering options. Either you can show them in dropdown or as inline. Choose your desired style from the right side. As we want to display only categories, it is ideal to go with the inline style.

Choose Between Dropdown and Inline

Here we can see the filter values selection option upon selecting the inline style. So we can choose the desired categories that we want to make available for filtering posts. 

Select Filterable Categories

Step – 4. Customize the Category Filter

Now, let’s explore further customization options of the category filter. At first, we can change the alignment by selecting from, left, center, and right. Moreover, we can change the “All Categories” text.

Change Text

However, the customization options are not limited only to the above-mentioned ones. You can get more customization by clicking on the “Styles” section. Here you have the following options:

  • Typography
  • Text Color
  • Hover Color
  • Background Color
  • Background Hover Color
  • Border Style and Color

Use these options to give an appealing look or match the filter with your website’s brand identity.

Moreover, you can adjust the border radius and box shadow options to make it more attractive and engaging.

Furthermore, you have the option to increase or decrease the gap between inline items and adjust the padding.

Here’s what I have done using the above-mentioned options. You can do even better without your own creativity.

Note: If you choose the dropdown filter instead of the inline you will see an additional customization option. It allows you to set the look of the dropdown items (filtering options) different than the parent item (All Categories).
