Many-to-Many Checkbox CHECKBOX
Displays options as checkboxes. Checking items establishes a many-to-many relationship, corresponding to JPA @ManyToMany. Suitable for scenarios with a small number of options.

Basic Usage
java
@ManyToMany
@JoinTable(name = "rel_main_ref",
joinColumns = @JoinColumn(name = "main_id"),
inverseJoinColumns = @JoinColumn(name = "ref_id"))
@EruptField(
edit = @Edit(title = "Related Options", type = EditType.CHECKBOX)
)
private Set<RefEntity> options;
RefEntitymust be an entity class annotated with@Erupt. Erupt will automatically read its data to populate the checkbox options.
Configuration
Use the checkboxType attribute of @Edit to control which columns of the related entity supply the option values:
java
public @interface CheckboxType {
String id() default "id"; // Column in the related entity used for storage (primary key)
String label() default "name"; // Column in the related entity used for display
String remark() default ""; // Column in the related entity used as the option description
}java
@ManyToMany
@JoinTable(name = "rel_main_ref",
joinColumns = @JoinColumn(name = "main_id"),
inverseJoinColumns = @JoinColumn(name = "ref_id"))
@EruptField(
edit = @Edit(title = "Related Options", type = EditType.CHECKBOX,
checkboxType = @CheckboxType(id = "id", label = "title", remark = "intro"))
)
private Set<RefEntity> options;
