The data-dismiss custom attribute marks those buttons and links that cause the dialog to close after click.Ī Bootstrap modal dialog box is initially hidden and pops up when some ad hoc JavaScript code is invoked. The footer conventionally contains the list of buttons to finalize the interaction between the user and the content. For example, the header typically contains the title of the dialog that Bootstrap styles through the modal-title class. The modal-content DIV is articulated in three parts each styled with a different Bootstrap class: modal-header, modal-body and modal-footer.Īny areas of the modal window can contain anything that is HTML compliant. This is the actual repository of the content presented to the user. The outermost container incorporates another DIV layer styled as modal-dialog which in turn includes another DIV container styled as modal-content. The ID of this element is the ID of the entire modal window. A modal window is fully contained in a DIV element styled as modal. It’s not different from previous versions of Bootstrap, but a quick look at its main characteristics is in order. Modal dialog boxes have been made a lot more configurable in Bootstrap 4 but the core HTML layout and the programming model around it has not changed much.

How to Create Modal Dialogs in Bootstrap 4 Having said that, let’s just see what it takes to create a modal dialog box in Bootstrap 4. In Bootstrap 4, instead, there’s plenty of documentation on how to use drop-down classes to display just any content that can fit into a DIV container. In any version of Bootstrap, drop-down elements are not limited to menus, though the documentation up until version 3.x seems to suggest just that. A second rule I apply to modals is: if the content is read-only and doesn’t require a strict acknowledgement from the user, then consider using a drop-down element instead. If I have to summarize my personal position about modals, it would be: if it’s not simple and short then it can’t go into a modal. There are no certain rules and facts about modals and this is enough to raise a flag whenever their use is considered or advocated during development. Finally, there are users that love modals and users who just hate them because they’re too intrusive. It all depends also on the amount of information being interacted in the diversion flow. It all depends on the details of the flow being interrupted and the diversion flow to inject. This is just a common use-case where modal dialog boxes may, or may not, be really helpful. It’s clearly doable, but sometimes we developers love shortcuts and users love shortcuts too. In a web scenario, without a modal dialog box, the entire flow is fairly convoluted as the operator needs to navigate to a different page, post its content, and then find a link to return back where she was. Once finished, she needs to go back to the original workflow. The operator is in the add-booking workflow but needs to take a diversion and temporarily switch to the add-user workflow. Suppose you are going to add a booking in the name of a user that doesn’t exist yet in the system.
A modal dialog box is often used to show optional information about an item being displayed on screen or to let users perform optional operations. There are many cases in which a modal dialog is helpful-for example, when you wish to get confirmation from the user about the operation just being started. In other words, a modal dialog box has the precise purpose of interrupting the ongoing workflow until its content is reviewed or interacted with.
