Hi Pierre,

yes. There's two ways in which this can be done, but neither is particularly easy.

1. When a new instance of your object is added to a document, you also add a bunch of preset sliders. This means the sliders can be disconnected by the user at will and replaced with other inputs.
2. You can override the attributes of an object and draw your own sliders and handle all mouse events yourself.

[1] is the more flexible approach from the users point of view, it's also less work. [2] can be done, an example of this would be the colour picker object, which has a bunch of sliders for the colour channels, or the Galapagos Gene Pool object which combines a bunch of sliders. It's quite difficult to make your own attributes, but there's an example in the Grasshopper SDK documentation ('Custom Attributes' in the Examples section, VB and C# examples provided). It doesn't tell you how to custom handle mouse events, but it's a start.
