My Issue/Question:
I want to create a multi select combo box that doesn't close when selecting an option. I am currently using the example from #1658 and it closes when I selected and option. Is there a way to keep the popup open when clicking the selectable inside of it?

Minimal, Complete and Verifiable Example code:

const char* items[] = { "AAAA", "BBBB", "CCCC", "DDDD", "EEEE", "FFFF", "GGGG", "HHHH", "IIII", "JJJJ", "KKKK", "LLLLLLL", "MMMM", "OOOOOOO", "PPPP", "QQQQQQQQQQ", "RRR", "SSSS" };
static const char* current_item = NULL;

if (ImGui::BeginCombo("##combo", current_item)) {
    for (int n = 0; n < IM_ARRAYSIZE(items); n++) {
        bool is_selected = (current_item == items[n]);
        
        if (ImGui::Selectable(items[n], is_selected)
            current_item = items[n];
            
        if (is_selected)
            ImGui::SetItemDefaultFocus();
    }
    ImGui::EndCombo();
}

Found solution

Use ImGuiSelectableFlags_DontClosePopups on selectables.

It is now possible to control this for Selectable, MenuItem() using the public API:

ImGui::PushItemFlag(ImGuiItemFlags_AutoClosePopups, false);
ImGui::MenuItem(....);
ImGui::PopItemFlags();
