I'm not entirely sure which part of that demo you're trying to replicate but you can create a marker with a popup like in this example. It's up to you to set where the marker is located on the map and/or get input from the user. You can use map.on('click, function () {...}) to place a marker on the map at the site of a user's click. You can see the basic idea in this example.

i want to marker is fixed and center of map and change location with drag map and not drag marker

You can listen for map.on('drag', callbackFn) and in the callback function, use map.getCenter() to get the center coordinate of the map. You can then update the position of the marker so that it will smoothly move as the map is panned.
