## What’s Changing and why?

The `host_template_types` array property for modules is being replaced with the `content_types` array property. The new `content_types` property is more robust and will allow for greater specificity regarding where modules can be used. Possible values for `content_types` include:

- `"ANY"` = Any of the areas listed below
- `"LANDING_PAGE"` = Landing pages
- `"SITE_PAGE"` = Site pages/templates
- `"BLOG_POST"` = Blog posts/templates
- `"BLOG_LISTING"` = Blog listing templates
- `"EMAIL"` = Emails and Email templates
- `"KNOWLEDGE_BASE"` = Knowledge base pages/templates
- `"QUOTE_TEMPLATE"` = Quotes templates
- `"CUSTOMER_PORTAL"` = Customer Portal templates
- `"WEB_INTERACTIVE"` = Web interactives
- `"SUBSCRIPTION"` = Subscription templates
- `"MEMBERSHIP"` = Membership templates

If a module is not to be used in any area within HubSpot, you would set the value to an empty array `[]` instead of `["NONE"]`.

You can view these values on our [Configuring a Module](https://developers.hubspot.com/docs/cms/building-blocks/modules/configuration) page within the [developer documentation](https://developers.hubspot.com/docs/cms).

Below is an example of the new `content_types` property in `meta.json` of a module:

```lia-code-sample
{
 "global" : false,
 "host_template_types" : ["PAGE", "BLOG_POST", "BLOG_LISTING"],
 "content_types" : ["SITE_PAGE", "BLOG_POST", "BLOG_LISTING", "QUOTE_TEMPLATE", "WEB_INTERACTIVE"]
 "module_id" : 136785808220,
 "is_available_for_new_content" : true
}

```

## What will happen to my existing modules?

Existing modules will not be affected initially as updates to the `host_template_types` property will sync to the `content_types` property allowing it to be updated accordingly while this change is rolled out. Developers should begin adopting this new property as the new values for `content_types` indicated above will not be available for the legacy property of `host_template_types`.

## When is this happening?

We are gradually rolling out this change over the next few weeks. Starting January 29th, 2024, all accounts will begin referencing this new property when assessing if a module will be available for use within areas inside of HubSpot (Email editor, Website page editor, etc…).

Any clues as to what WEB\_INTERACTIVE might include?

Hello, today is 2024, Jan 30th and the `content_types` property is not available yet on our environment.  
It was stated that:  
Starting January 29th, 2024, all accounts will begin referencing this new property when assessing if a module will be available for use within areas inside of HubSpot  
This is annoying because we then have a lot of errors `Error: CSS and Javascript are not allowed on email modules` when trying to push to our QA Hubspot environment. It’s like `content_types` is not considered at all.  
Do you know when `content_types` will be usable?
