How to do dynamic construction in Flask

Dynamic Construction

Dynamic Construction refers to the rendering of certain objects upon the occurrence of an event.

This may be useful to show a search bar when the search button has been pressed or to show a resource-intensive object when required.

Code

The following example shows how Dynamic Construction can be carried out.

def navigation_bar():
    return Navbar(...)
nav.register_element('navigation_bar', navigation_bar)

This example shows the use of register_element, a function that registers the element to be shown. The parameters are the element ID and the function to be called. Whenever the element needs to be shown, the navigation_bar() function will be called.
