If the branches are hanging, it isn't receiving enough light. Another sign of same problem are the sets of leaves spaced far apart = long internode. I see that on new growth, so it is still not getting enough light.

There is a plant with common name 'trailing or weeping jade' (Senecio jacobsenii - Kleinia petraea) but your plant seems to be Crassula ovata.

Plus it looks like it’s never been pruned, and has been allowed to grow in less than ideal light conditions as Rina suspects. It may well appear ‘healthy’ but etiolated plants tend to be weaker than strongly grown ones in better conditions.

The lax growths will never revert to being ‘normal’ so any new growths will be tighter and more upright in appearance, provided better light is given....but these will be heavier and will grow only at the ends of those spindly or downward drooping branches. This has the effect of weighing down the already thin and unsupportive growths even more!

Pruning the gangly growths drastically maybe be your option to convert it into a more usual upward growing Crassula ovata when the bushier growths can be supported by the strongest limbs.
