I'm tryng to display categories and subcategories on a cms page

<?php 

    $categories = Mage::getModel('catalog/category')

        ->getCollection()

        ->addAttributeToSelect('*')

        ->addIsActiveFilter();

    foreach ($_categories->getStoreCategories() as     $_category) { 

        $category = Mage::getModel('catalog/category'); 

        $category->load($_category->getId()); 

        $subcategories = explode(',', $category->getChildren()); 

?> 

        <dl> 

          <dt><?php echo $this->htmlEscape($_category->getName()); ?>

          </dt> 

          <dd> 

            <ol> 

              <?php 

                foreach ($subcategories as $subcategoryId) { 

                  $category->load($subcategoryId); 

                  echo '<li><a href="' . $category->getURL() . '">' . $category->getName() . '</a></li>'; 

                } 

              ?> 

            </ol> 

          </dd> 

        </dl> 

    <?php

      } 

    ?>

But this is returning me a fatal error Fatal error: Call to a member function getStoreCategories() on null on line 5

You can try below code for display all store category and subcategories.

<?php

    $_helper = Mage::helper('catalog/category');

    $categories = $_helper->getStoreCategories();



    foreach ($categories as $_category) {

        $category = Mage::getModel('catalog/category')->load($_category->getId());

        $subcategories = $category->getChildrenCategories();

        ?>

        <dl>

            <dt><?php echo $this->htmlEscape($_category->getName()); ?></dt>

            <dd>

                <ol>

                    <?php

                    foreach ($subcategories as $_subcategory) {

                        echo '<li><a href="' . $_subcategory->getURL() . '">' . $_subcategory->getName() . '</a></li>';

                    }

                    ?>

                </ol>

            </dd>

        </dl>

        <?php



    }

    ?>

Let me know if you have any query from above.

Please follow the below steps:

Step 1: Create new_list.phtml in frontend/your_theme/default/template/catalog/category and paste the below code :

     ================code starts here================



<div class="block block-list block-categories">

    <div id="block-categories" class="block-title active">

        <strong><span>Categories </span></strong>

    </div>  

    <div id="leftnav" class="block-content" style="display:block">

        <?php $helper = $this->helper('catalog/category') ?>

            <?php $categories = $this->getStoreCategories() ?>

        <?php if (count($categories) > 0): ?>

            <ul id="leftnav-tree" class="level0">

                <?php foreach($categories as $category): ?>

                    <li class="level0<?php if ($this->isCategoryActive($category)): ?> active<?php endif; ?>">

                        <a href="<?php echo $helper->getCategoryUrl($category) ?>"><span><?php echo $this->escapeHtml($category->getName()) ?></span></a>

                        <?php //if ($this->isCategoryActive($category)): ?>

                            <?php $subcategories = $category->getChildren() ?>

                            <?php if (count($subcategories) > 0): ?>

                                <ul id="leftnav-tree-<?php echo $category->getId() ?>" class="level1">

                                    <?php foreach($subcategories as $subcategory): ?>

                                        <li class="level1<?php if ($this->isCategoryActive($subcategory)): ?> active<?php endif; ?>">

                                            <a href="<?php echo $helper->getCategoryUrl($subcategory) ?>"><?php echo $this->escapeHtml(trim($subcategory->getName(), '- ')) ?></a>

                                             <?php $secondLevelSubcategories = $subcategory->getChildren() ?>

                                             <?php if (count($secondLevelSubcategories ) > 0): ?>

                                <ul id="leftnav-tree-<?php echo $subcategory->getId() ?>" class="level2">

                                    <?php foreach($secondLevelSubcategories as $secondLevelSubcategory ): ?>

                                        <li class="level2<?php if ($this->isCategoryActive($secondLevelSubcategory )): ?> active<?php endif; ?>">

                                            <a href="<?php echo $helper->getCategoryUrl($secondLevelSubcategory ) ?>"><?php echo $this->escapeHtml(trim($secondLevelSubcategory ->getName(), '- ')) ?></a>

                                        </li>

                                        <?php endforeach; ?>

                                </ul>

                                <script type="text/javascript">decorateList('leftnav-tree-<?php echo $category->getId() ?>', 'recursive')</script>

                            <?php endif; ?>

                                    <?php endforeach; ?>

                                </ul>

                                <script type="text/javascript">decorateList('leftnav-tree-<?php echo $category->getId() ?>', 'recursive')</script>

                            <?php endif; ?>

                        <?php //endif; ?>

                    </li>

                <?php endforeach; ?>

            </ul>

            <script type="text/javascript">decorateList('leftnav-tree', 'recursive')</script>

        <?php endif; ?>

    </div>

</div>



          ===============code ends here===============

Step 2 : Call new_list.phtml in your CMS page or static block:

{{block type="catalog/navigation" name="catalog.category" template="catalog/category/new_list.phtml"}}

Hope, it will help.
