Hello,
Sorry for the inconvenience.
Under the Single Product Layout Builder, there are three widgets available related to Brand:
Brands
Product Brand Information
Product Brands
See this image for reference: https://ibb.co/hBgFqcq
Further, regarding the Attribute to have alone access and drag them anywhere, the thing is the Attribute Swatches or you can say the Attributes themselves under the Product Layout Builder are added through Product Add to Cart widget and right now it doesnโt have an option to make a separate selection or addition for these Swatches unfortunately. So, when you add this Add to Cart widget the Swatches comes along with that. As you know, the Additional Information tab shows the Attributes information in plain text, so you can add that widget to show your Attributes in plain Text through the following widget: Product Additional Information Table
Hope you can understand !
Best Regards.
