Optimizations

Plugin configuration 87% from 29 tests

readme.txt 88% from 16 tests

You should put a lot of thought into formatting readme.txt as it is used by WordPress.org to prepare the public listing of your plugin
These attributes need to be fixed:
  • Screenshots: Screenshot #1 (Brand new dropdown menu options page.) image required
  • Tags: There are too many tags (15 tag instead of maximum 10)
You can look at the official readme.txt

dropdown-menu-widget/shailan.DropDownMenu.php 85% from 13 tests

The main file in "Dropdown Menu Widget" v. 1.9.7 serves as a complement to information provided in readme.txt and as the entry point to the plugin
You should first fix the following items:
  • Text Domain: The text domain is optional since WordPress version 4.6; if you do specify it, it must be the same as the plugin slug
  • Main file name: Name the main plugin file the same as the plugin slug ("dropdown-menu-widget.php" instead of "shailan.DropDownMenu.php")
