Sidebar widget

Hi Nayan,

Is that recent post widget or just a regular text widget?

Let me know.

I am using List category posts widget, I don't no how to edit

Are you using a plugin already to display that?

Can you provide a link to your site?

I just changed the plugin with "Category Posts Widget", but I want thumbnail neatly in row with title

Are you sure the plugin doesn't have the settings to change the thumbnail layout?
Looks achievable from the screenshots on this page? https://wordpress.org/plugins/category-posts/screenshots/

If not you might want to ask the question on the plugin support forum. Looks like the author is quite active on there as well.

Hope this helps!
