Select all button not working properly in multiple select enabled

while select all is selected and selected values are reset the select all button is not deselected

while select all is selected and 1 option deselected the select all button is not deselected

@siva04 the state of the select all checkbox is controlled via

ngx-mat-select-search/src/app/mat-select-search/mat-select-search.component.ts

Lines 177 to 180 in da14301

	@Input() toggleAllCheckboxChecked = false;
	/** select all checkbox indeterminate state */
	@Input() toggleAllCheckboxIndeterminate = false;

do you want to fix this in the demo?

1. @macjohnny i can take this bug. Is it only on demo page or somewhere else?
2. Basically is there somekind of discord or some channel when we can get in touch? I would like to ask about contributions. What can i take? Are there any specific rules etc.? Because i would like to take something more serious. But of course... baby steps. Don't want to take the biggest feature. Becasue i need to do some warmups to be more familiar with repo code :)

@swierzbicki thanks for offering help, thats much appreciated.

1. i think the problem is on the demo page, since the select-all control in ngx-mat-select-search does not have any logic
2. you could connect with me on linkedin or via the email on bithost.ch/team
