When this plugin is installed, the following 9 blocks are registered and can be used not only in the block editor but also in the site editor (tested on WordPress 6.4.2). In principle, each block can be configured with basic styles such as text color, background color, border, and white space, and in some cases it is also possible to set shadows and icons. There are also some that have simple animations set. 
Below is a brief explanation of each block. 
1 Design Title 
A block that allows you to style HTML heading tags. In addition to the normal style, we have prepared a type that allows you to insert a circular marker, and a type that allows you to add sub copies and icons. 
2 Design Text Control 
This is a block that allows you to style text controls and text area controls for HTML input elements. This time, we have prepared a normal box type and a line type. It is now possible to display required inputs, and it is a block that can be used for validation checks as an inner block of the Form Send Block. 
3 Design CheckBox 
This is a block that allows you to style checkboxes in HTML input elements. Check animation. At the moment, we only have one type available, but we plan to gradually offer other variations in the future. 
4 Design Select 
A block that allows you to style HTML SELECT elements. It boasts that the selection element moves with a slightly fancy animation. Supports single selection and multiple selection. 
5 Design Process 
A block for displaying the input process of form input. It is assumed that it will be used as an inner block for the Guest Contact Block, which will be released soon, and this block will not work on its own. 
6 Code HighLight 
This block allows you to enter code in the text area in edit mode and highlight it on the front end. This block uses the Google Code Prettify library for highlighting. 
7. Design Table 
Displays the contents of a form object placed on a web page as a data source. 
It is intended to be installed in the input confirmation form as an inner block of Form Send Blocks, which will be released soon. 
8. Design Button 
You can choose between regular buttons and submit buttons inside form elements. When you select the regular button, you can select a link to a fixed page and transition to that page. 
9. Design Group 
– Its main function is to store blocks and set their arrangement. 
The placement can be selected according to the CSS display property block, flex(row), flex(column), or grid. If you select grid, you can set various grid styles. 
– Compatible with block themes, you can select contentSize and wideSize in the layout clause of theme.json, and you can also set the width to match the content width or freely set the width. 
– By setting it to “Make it a menu”, it will become a hamburger button in mobile mode (displayed on devices with a width of 767px or less), and when you click it, it will stick out from the left. 
– These settings can be set separately for desktop mode (displayed on devices with a width of 768px or more) and mobile mode (displayed on devices with a width of 767px or less). 
– By setting it to be movable, you can adjust the placement by dragging. With this feature installed, the old version of Draggble Box has been discontinued. 
10. Design Radio 
This block allows you to set styles for HTML radio button input elements. This time, we have prepared a normal radio button type and a button type. It is possible to add a button to deselect the element. 
11. Design Calender 
– This block allows you to select and enter a date from a calendar. You can choose the start day of the week to be Sunday or Monday. 
– You can also set the display of holidays. To set holidays, you need to obtain an API key for the Google Calendar API.
This plugin contains the ability to extend the core blocks: core/paragraph, core/image, core/table, core/list, and core/quote.
