Issue description

Current behavior:

Currently, the nb-select component does not support the following features:

1. Select All
2. Unselect All, and
3. Type ahead search features

Expected behavior:

It would be provide a great usability boost if the above 3 features are supported by the nb-select component.

Bold plus! Search feature for select is very necessary!

hi @ashwin-kambli !
We are currently working on our 5th version of Nebular where the autocomplete component will be available (https://github.com/akveo/nebular/pull/1947). Also, we will consider the p. 1 and 2 of your issue, thank you for the feedback.

If you cant wait till 5th version I've found angular2-multiselect-dropdown useful with following css in @theme/style/style.scss for nebular look and feel that does multiselect, select all and search operation

.cuppa-dropdown {
width: 300px;
display: inline-block;
color: nb-theme(text-basic-color);
box-shadow: none;
border: none !important;
left: 15px;
.list-filter {
  border: 1px solid nb-theme(color-primary-500);
  input {
    background-color: nb-theme(background-basic-color-1) !important;
    color: nb-theme(color-basic-active);
  }
  input:focus {
    outline: none;
  }
  .fa {
    color: nb-theme(background-basic-color-2) !important;
  }
}
button.c-btn {
  color: nb-theme(color-basic-active);
  box-shadow: 0 0 0 transparent !important;
  border-color: nb-theme(color-primary-500) !important;
  border-radius: 5px !important;
  border-style: solid !important;
  background-color: nb-theme(background-basic-color-2) !important;
  text-align: left;
}
.selected-list {
  box-shadow: none !important;
  border: none !important;
}

.dropdown-list {
  position: absolute;
  padding-top: 14px;
  width: 100%;
  z-index: 9999;
  ul {
    li:hover {
      color: nb-theme(color-primary-hover) !important;
      background-color: nb-theme(background-basic-color-1) !important;
    }
  }
}

.list-area {
  background-color: nb-theme(background-basic-color-1) !important;
  color: nb-theme(text-basic-color) !important;
  box-shadow: none;
  border: none !important;

}
.pure-checkbox input[type="checkbox"] + label {
  color: nb-theme(text-basic-color) !important;
}
.pure-checkbox input[type="checkbox"] + label:hover {
  color: nb-theme(color-primary-hover) !important;

hi @ashwin-kambli !
We are currently working on our 5th version of Nebular where the autocomplete component will be available (#1947). Also, we will consider the p. 1 and 2 of your issue, thank you for the feedback.

Where is documentation?

[egmed]

So when the 'Search the dropdown' feature will be ready? anytime soon?

[Xymanek]

The docs are here: https://akveo.github.io/nebular/docs/components/autocomplete/overview

However, it doesn't seem like there is a way to limit the input only to the provided options, neither to get an array out of the input field
