Let's say you have created a number custom field in the "Fields" tab of the listing type and named it Price
While adding the listing, the user will type the price unformatted e.g 5000
But in listing page you want to display the price in the correct format and also add the currency e.g $5,000
How to achieve this depends on where you are displaying the price
Edit listing type > single page tab > cover details > to the right click the pre-set option named "Price"
Click on it, under the "Field" dropdown, choose the price field
Under "Format" dropdown, choose "Number"
Under Prefix or Suffix add the currency of your choice
Edit listing type > preview card > under "Head buttons" click "Add new", click on the input and press @
You will get a dropdown of all the fields available for that listing type.
Search for the name of your price field and choose the .formatted option to add it. Once you add the field, add the currency before or after it
Edit listing type > single page > content and tabs > choose a tab where you want to display the price > under "Add a new block" dropdown, choose table or detail block, for this example, we'll choose a table.
Click on the table, and choose "Add row"
Under label add "Price"
Under "Fields to use" choose the price field
Under "Content" replace [[field]] with this shortcode
You can change the $ sign inside the prefix="$" to the currency symbol of your choice
Edit listing type > single page > content and tabs > choose a tab where you want to display the price
Under "Add a new block" dropdown, choose shortcode block
In the shortcode block add the shortcode
Keep in mind that the [[price]] part depends on the field key of your custom field. When you initially created the field in the "Fields" tab of the listing type, you are asked to type the name and field key. If the field key is let's say monthly-price
then the shortcode should reflect that e.g
Edit listing type > search forms > advanced/basic form > edit the range facet > add the currency in the prefix or suffix fields, and enable the "Format" checkbox
