If the option to add new blog attributes to the Blog CMS Collection Settings in Webflow is locked or grayed out, it could be due to a few reasons. Here are some possible solutions:
1. Check your site plan: The ability to add new attributes to the Blog CMS Collection Settings may be restricted based on your Webflow plan. Make sure that your plan allows for custom CMS attributes. If you're on a free plan or a plan that doesn't include this feature, you may need to upgrade your plan.
2. Check your user permissions: Ensure that you have the appropriate permissions to make changes to the CMS settings. If you're working on a team or collaborating with others, make sure that you have the necessary access.
3. Verify CMS item limits: The number of attributes you can add may be limited by the CMS item limit based on your plan. Check if you have reached the maximum limit of CMS items for your account. If you have, you may need to either delete unused CMS items or upgrade your plan to increase the limit.
4. Duplicate and modify the existing attribute: If you're unable to add new attributes, but need additional fields, a workaround is to duplicate an existing attribute and modify it according to your needs. For example, if you have an attribute for "Author," duplicate it and rename it as "Co-author" or any other specific attribute you require.
5. Contact Webflow support: If none of the above solutions work, reach out to Webflow support for further assistance. They will be able to investigate the issue and provide you with specific guidance based on your account and website configuration.
Remember to regularly update your Webflow CMS plan and review the available features to ensure you have the necessary capabilities to manage your website content effectively.
