How to modify border title once the widget is instantiated?

Hello @miguelmota, I am assuming you are asking about the container title? You should be able to utilize the dynamic layout feature.

In short you specify an ID for the container when creating it by passing this option:

termdash/container/options.go

Lines 308 to 320 in 68bf056

 // ID sets an identifier for this container. 
 // This ID can be later used to perform dynamic layout changes by passing new 
 // options to this container. When provided, it must be a non-empty string that 
 // is unique among all the containers. 
 func ID(id string) Option { 
 	return option(func(c *Container) error { 
 		if id == "" { 
 			return errors.New("the ID cannot be an empty string") 
 		} 
 		c.opts.id = id 
 		return nil 
 	}) 
 } 

And then you can use the container.Update function, specifying the same ID and providing any set of new options, including a new title:

termdash/container/container.go

Lines 229 to 235 in 68bf056

 // Update updates container with the specified id by setting the provided 
 // options. This can be used to perform dynamic layout changes, i.e. anything 
 // between replacing the widget in the container and completely changing the 
 // layout and splits. 
 // The argument id must match exactly one container with that was created with 
 // matching ID() option. The argument id must not be an empty string. 
 func (c *Container) Update(id string, opts ...Option) error { 

However if you are asking about title of a specific widget, that might be different, please let me know.
