How to enable a Leaflet Draw tool programatically

Unleash the Power: Programmatically Controlling Leaflet Draw Tools

Leaflet? It’s not just a map library; it’s a gateway to crafting seriously cool, interactive web maps. And when it comes to adding drawing and editing superpowers, Leaflet.draw is where the magic happens. Sure, the default toolbar is handy, but what if you want total control? What if you need to trigger drawing tools based on user roles or some other behind-the-scenes logic? That’s where programmatic activation comes in, and trust me, it’s easier than you think.

Leaflet.draw: More Than Just a Toolbar

Leaflet.draw is essentially a plugin that bolts onto Leaflet, letting users draw all sorts of vector goodies – lines, shapes, circles, you name it – right on the map.

But we’re going to go deeper than just clicking buttons.
