Shortly before publishing an article on Blogger, we usually use the post preview feature to check the post order that we just created. Well, usually there are certain widgets (such as Featured Post, Featured by Label, etc.) which are actually only displayed on the main page (homepage), suddenly appearing on the Post Preview page. Personally, the appearance of this unwanted widget can be very distracting while on the page. How can I prevent the widget from appearing during Post Preview? Here's how!
How to remove certain widgets on the Post Preview page
Please go to the blog dashboard, then go to Theme> Edit HTMLClick the Jump to Widget dropdown menu , then select the widget you want to hide on the post preview page (in this tutorial, for example what you want to hide is the Featured Post widget).

After being brought to the Featured Post widget markup, please place the following conditional tags like this:
<b: if cond = 'data: view.isPreview'> <b: else />
--- Featured Post widget code here ---
</ b: if>
Like the following picture:

After that, save Theme!
Please do the same with other widgets that you want to hide on the Post Preview page.
If anyone has another method besides the above method for this problem, please share it in the comments column.

So many tutorials this time, hopefully useful!
