ContentElement: Content Element
In DavidBarke/QWUtils: Useful Methods For Programming with Shiny

Content Element

new(id, title, ..., session = shiny::getDefaultReactiveDomain, footer = NULL, closeable = FALSE, collapsible = TRUE, width = 12, height = NULL, tabPanel_list = NULL)

`id`	The content element's id.
`title`	Title for the tabBox.
`...`	`tabPanel` elements to include in the tabset.
`session`
`footer`	Footer below the tabBox.
`closeable`	If `TRUE`, the content element is closeable.
`collapsible`	If `TRUE`, the content element is collapsible.
`width`	The width of the box, using the Bootsgrap grid system. This is used for row-based layouts. The overall width of a region is 12, so the default valueBox width of 4 occupies 1/3 of that width. For column-based layouts, use `NULL` for the width; the width is set by the column that contains the box.
`height`	The height of a box, in pixels or other CSS unit. By default the height scales automatically with the content.
`tabPanel_list`	Instead of using the `...` argument for passing `tabPanel` elements, you may pass a list of `tabPanel` elements in this argument.

append_tab(tab, select = FALSE, closeable = FALSE)

`tab`	The `tabPanel` element to be added.
`select`	Should `tab` be selected upon being inserted?
`closeable`	If `TRUE`, the added tab is closeable via an action button.

hide()

Hide this content element.

get_id()

Get the content element's id.

show()

Show the content element.

show_by_action_button(id, session = shiny::getDefaultReactiveDomain())

Show the content element, if the actionButton with inputId == id is clicked. session is the session, in which the actionButton was defined.

remove_tab(target)

Dynamically remove a tabPanel.

`target`	The `value` of the `tabPanel` that you want to remove.

ui(hidden = TRUE)

Get the ui (similar to tabBox) associated with this content element. You should only call this function once. If hidden, the ui starts in a hidden mode (see hidden). Use this$show() for showing the ui.

update_tab(selected)
