Can I simulate particle system in edit mode without clicking on hierarchy?

To show the particle system such as Firework, i have to click
FireWork in the hierarchy. If not, it won’t simulate in edit mode.
It is so inconvenient to show all the elements in edit mode.

You must actively choose a particle system object in hierarchy in order to preview the effect. Since you are making a firework effect, that means you should have more than 1 particle sys object to compose the complete firework effect. Supposedly you have a parent object which contains all the child particle sys objects, you can preview all particle sys objects at once under that parent object if you add a particle sys component with all modules (most importantly emission and renderer modules) disabled to that parent object.
