# HTML ### Custom HTML ^_*\[Pro]* You can completely rewrite the HTML of the popup if you want, entering your own format and entering in custom tags that will insert dynamic content. [See an example here](https://wpmaps.mapster.me/examples/mapster-wp-map/sample-custom-html-popup/).

### Dynamic Tags ^_*\[Pro]* By using the tags indicated in the description of the field, you can enter in tags that will be replaced in the front end with data of that feature post. These include: * Header Text `{header}` * Image URL `{image_url}` * Content `{content}` * Button Link `{button_url}` * Button Text `{button_text}` * Post Title`{post_title}` ### Custom Fields ^_*\[Pro]* You can also reference ACF fields or custom properties that you've added to your data, similar to elsewhere in the plugin. For custom properties, add the name of the field:

So, in the case of the above, if you wanted to add "name" into your popup, you would add: ```

Some custom {name} HTML

``` For ACF fields, use the field name (not the field ID). So for the following:

If you wanted to add the "School name", you would add: ```

My custom {school_name}
