Introduction
You may want to separate your fields into sections, each with a heading and description. To do this, you can use a section component:Adding an icon to the section’s header
You may add an icon to the section’s header using theicon() method:
Positioning the heading and description aside
You may use theaside() to align heading & description on the left, and the components inside a card on the right:
Collapsing sections
Sections may becollapsible() to optionally hide long content:
collapsed() by default:
collapsible() and collapsed() methods accept a boolean value to control if the section should be collapsible and collapsed or not:
Persisting collapsed sections in the user’s session
You can persist whether a section is collapsed in local storage using thepersistCollapsed() method, so it will remain collapsed when the user refreshes the page:
id() of that section to prevent an ID conflict:
persistCollapsed() method accepts a boolean value to control if the section should persist its collapsed state or not:
Deferring the loading of section content
If the content of a section is expensive to render, you can pass aSchema object to schema() and use deferLoading(). This is particularly useful for a section that is collapsed by default. The section and its header will render immediately, while its content will not be loaded until the section is expanded and the content enters the viewport:
Compact section styling
When nesting sections, you can use a more compact styling:compact() method accepts a boolean value to control if the section should be compact or not:
Secondary section styling
By default, sections have a contrasting background color, which makes them stand out against a gray background. Secondary styling gives the section a less contrasting background, so it is usually slightly darker. This is a better styling when the background color behind the section is the same color as the default section background color, for example when a section is nested inside another section. Secondary sections can be created using thesecondary() method:
secondary() method accepts a boolean value to control if the section should be secondary or not:
Inserting actions and other components in the header of a section
You may insert actions and any other schema component (usually prime components) into the header of a section by passing an array of components to theafterHeader() method:
Inserting actions and other components in the footer of a section
You may insert actions and any other schema component (usually prime components) into the footer of a section by passing an array of components to thefooter() method:
Using grid columns within a section
You may use thecolumns() method to easily create a grid within the section:
