Header¶

The Header element is used as a header row.

Example

Collapsible¶

By default this is false. Setting this to true will allow the form header to "collapse/uncollapse" (Hide/Show) elements below it when tapped.

header { collapsible = true }

All Collapsed¶

By default this is false. This indicates if elements under the form header are collapsed or not.

header { allCollapsed = true }

Set All Collapsed Later¶

Use setAllCollapsed(collapse, formBuilder) to collapse/uncollapse elements after initialization. Collapse or uncollapse all elements under the header until the next header.

// Reverse Collapse
header.setAllCollapsed(!header.allCollapsed, formBuilder)

// Reverse Collapse for all headers
formBuilder.elements.forEach {
    if (it is FormHeader) {
        it.setAllCollapsed(!it.allCollapsed, formBuilder)
    }
}

Example¶

Kotlin¶

header { title = "I'm a header row"; collapsible = true }

Java¶

List<BaseFormElement<?>> elements = new ArrayList<>();
FormHeader header = new FormHeader("I'm a header row");
elements.add(header);
