This template used svelte to create the store and share the states variable between the components. Store files can be found via /src/stores/

/src/stores/
├─ appOptions.js            // global app option states
├─ appSidebarMenus.js       // global app sidebar menu list
├─ appTopNavMenus.js        // global app top nav menu list
└─ appVariables.js          // global app variable (fetched from css / font variables)

You can use the global app option from /stores/apOptions.js

<script>
  import { onMount, onDestroy } from 'svelte';
  import { appOptions } from '/src/stores/appOptions.js';

  onMount(async () => {
    // available app option
    $appOptions.appBoxedLayout = true;
    $appOptions.appSidebarToggled = true;
    $appOptions.appSidebarCollapsed = true;
    $appOptions.appSidebarMobileToggled = true;
    $appOptions.appSidebarMobileClosed = true;
    $appOptions.appSidebarHide = true;
    $appOptions.appHeaderToggled = true;
    $appOptions.appHeaderSearchToggled = true;
    $appOptions.appHeaderHide = true;
    $appOptions.appContentFullHeight = true;
    $appOptions.appContentClass = 'p-0';
    $appOptions.appTopNav = true;
    $appOptions.appFooter = true;
    $appOptions.appFooterFixed = true;
    $appOptions.appThemePanelToggled = true;
    $appOptions.appVh100 = true;
  });
  
  onDestroy(() => {
    // set to default before leave the page
    $appOptions.appFooter = false;
  });
</script>

You can use the global app variables (css color / font family) from /stores/appVariables.js

<script>
  import { onMount, onDestroy } from 'svelte';
  import { appVariables } from '/src/stores/appVariables.js';

<!-- html -->

Set the app sidebar menu list from from /stores/appSidebarMenus.js

// single level structure
{
  'url': '/',
  'icon': 'ph:rocket-duotone',
  'text': 'DASHBOARD'
},

// multi level structure 
{
  'icon': 'ph:envelope-duotone',
  'text': 'EMAIL',
  'children': [{
      'url': '/email/inbox',
      'action': 'Inbox',
      'text': 'INBOX'
    }, {
      'url': '/email/compose',
      'action': 'Compose',
      'text': 'COMPOSE'
    }, {
      'url': '/email/detail',
      'action': 'Detail',
      'text': 'DETAIL'
    }]
}

The default theme color is set to the teal color. You may change it from /src/scss/_variables.scss

// LINE 84
$theme:        $teal !default;
***IMPORTANT***
You might need to remove the <AppThemePanel /> component from /routes/+layout.svelte.

This is because app-theme-panel will store a localStorage variable and append the theme class automatically when page load if you have select any theme color before from theme panel.

To enable RTL mode, follow these steps:

  1. Navigate to the /src/scss/_variables.scss file in your code editor.
  2. Find the $enable-rtl variable and change its value to true:
    $enable-rtl: true;
    
    This will enable RTL mode for your application.

Global Variables

The /src/scss/_variables.scss file contains the variables that control the styles of your application.

To edit these variables, navigate to the /src/scss/_variables.scss file in your code editor and modify the values of the variables to suit your needs.

<!-- global variable -->
/src/scss/_variables.scss

We have created the common re-usable card bootstrap component for this template. You may found the card component via /src/components/bootstrap/

//usage 
<script>
  import Card from '$components/bootstrap/Card.svelte';
  import CardHeader from '$components/bootstrap/CardHeader.svelte';
  import CardHeaderBtn from '$components/bootstrap/CardHeaderBtn.svelte';
  import CardBody from '$components/bootstrap/CardBody.svelte';
</script>

<Card>
  <CardHeader class="with-btn">
    ...
    <CardHeaderBtn />
  </CardHeader>
  <CardBody>...</CardBody>
  <CardFooter>...</CardFooter>
</Card>

You may use the default bootstrap data attribute like data-bs-toggle="dropdown" OR import the required modules from bootstrap.

// usage example
<script>
  import { onMount } from 'svelte';
  
  onMount(async () => {
    let bootstrap = await import('bootstrap');
    new bootstrap.ScrollSpy(document.body, {
      target: '#sidebar-bootstrap',
      offset: 200
    });
  });
</script>
